New Delhi: Delhi Police Commissioner BS Bassi on Monday said that Thiruvananthapuram MP Shashi Tharoor may be summoned for further probing in his wife Sunanda Pushkar's death case.

Speaking to ANI, Bassi said that Special Investigation Team (SIT) has analysed Sunanda's son Shiv Menon's statement and based on the information gathered, Shashi Tharoor is expected to be summoned again and will be asked to assist in the probe.

Shiv Menon had appeared before the SIT office in South Delhi's Vasant Kunj and was questioned in connection with the murder case. Police sources had said that Menon was asked how the relationship was between Tharoor and Sunanda.

Tharoor along with his staff members and close friends has been quizzed by the Delhi Police so far.

Former Samajwadi Party leader Amar Singh and senior journalist Nalini Singh have also been questioned.

52-year-old Sunanda was found dead in her suite at a five-star hotel in south Delhi on the night of January 17, 2014, a day after she was involved in a spat with Pakistani journalist Mehr Tarar on micro-blogging website Twitter over the latter's alleged affair with Tharoor.
